 Title    Darstellung, Eigenschaften und elektronische Raman-Spektren von Di(bromo)phthalocyaninatometallaten(III) der Eisengruppe  
 Abstract    Synthesis, P ro p erties an d E lectronic R am an Spectra of D i(b ro m o)p h th alo cy an in ato m etalates(III) of the Iron G roup E lem ents Svend Sievertsen, H en d rik Schlehahn, H ein er H om borg Low spin di(bromo)phthalocyaninatometalates of tervalent iron, ruthenium and osmium ([MBr2Pc2-]') are formed by the reaction of [FeBrPc2~] or H[MBr2Pc2 ] (M = Ru, Os) with ex­ cess bromide in DMF or THF and isolated as ("Bu4N)+ salts. The electronic spectra show the typical J i-jr*-transitions (B, Q, N region) of the Pc2~ ligand together with a number of extra bands due to trip-multiplett and (Pc, Br — » M)CT transitions. vs(MBr) is observed in the resonance Raman (RR) spectrum (RR enhanced for M = Fe, Ru) at 161 cm-1 (Fe), 183 cm4 (Ru) and 192 cm-1 (Os), vas(MBr) at 251 cm4 (Fe), 234 cm-1 (Ru) and 218 cm-1 (Os) in the FIR spectra. The RR spectra obtained by excitation at low absorbance between the B and Q region are dominated by the intraconfigurational 'T 7 — > r 8" transition due to spin orbit split­ ting of the 2T2g ground state for Fe at 583 cm-1, Ru at 1026/1050 cm-1 and Os at 3131 cm4 . In the MIR resp. NIR spectra vibronically induced transitions are observed for the Ru or Os complex.
